CalmOrNot

I've been doing shamanic breath work for almost 6 months now. For the past 4 weeks I've noticed that I'm unable to sustain for more than 15 minutes and I'm unable to enter deep states on consciousness. Also I've started to feel blockages in my body and I'm unable to breath past them as they start to contain me and my breath work gets restricted. Has anyone else here experienced the same? It would be great if you could throw some light on it. Thanks!

Hi, I've been meditating for about 6 months now. Recently, I started with the technique of 'Do nothing' accompanied with SDS. 10 minutes into my meditation session and I either find myself leaning forward/backwards or slouching. This creates a lot of confusion because If I don't move I'll be promoting bad posture and If I move then I'm completely defeating the purpose of SDS. Even If I do correct my posture I find myself slouching of leaning backwards after 5-7 minutes. If you have any suggestions, I'm all ears. Thanks!
